An airplane is flying on a flight path that will take it directly over a radar tracking station. if the distance between the tracking station and the airplane is decreasing at a rate of 400 miles per hour when the distance between them is 10 miles, what is the speed of the plane if the plane is always 3 miles above the ground?

The speed of planes is 419.31 miles per hours

Explanation:

Given that

S= 10 miles

And we have to find .

From triangle ABC

by differentiating with respect to time t

Now when S=10 miles then

x= 9.53 miles

So

So the speed of planes is 419.31 miles per hours

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
